Answer:
0.5 atm is equal to 380mmHg.
Explanation:
For every 1 atm, it is equal to 760mmHg.
Therefore, 0.5 atm is 760/2, which is 380mmHg.
Answer:
2.33×10¯¹⁶ g of forsterite
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms. This equally means that 1 mole of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
1 mole of forsterite (Mg2SiO4) = (24×2) + 28 + (16×4)
= 48 + 28 + 64
= 140 g
Finally, we shall determine the mass of forsterite that contains a million oxygen atoms.
140 g of forsterite (Mg2SiO4) contains 6.02×10²³ atoms.
Therefore, Xg of forsterite (Mg2SiO4) will contain 1×10⁶ atoms of oxygen i.e
Xg of forsterite (Mg2SiO4) =
(140 × 1×10⁶) /6.02×10²³
= 2.33×10¯¹⁶ g
Therefore, 2.33×10¯¹⁶ g of forsterite contains a million oxygen atoms..
Answer:
Listed below
Explanation:
Analytical chemistry: using quality and quantity observations to identify and measure physical and chemical properties of substances.EXAMPLE: medical diagnosis
Physical chemistry: Combination of physics and chemistry. EXAMPLE:nitric acid eating through wood.
Organic chemistry: Studying of compounds containing carbon in them. EXAMPLE: there are different products that make use of this type of chemistry for example perfumes,gasoline and many more.
Inorganic chemistry: Studies materials without carbon i them. EXAMPLE: Metals AND Gases.
Biochemistry: studies chemical processes occurring in living organisms. EXAMPLE: Human bodies and muscles
Theoretical chemistry: provides explanations to chemical and physical observation. EXAMPLE: Concepts of chemical reactions
